Your post, if that is what you meant, was ill-expressed. Would you have said 'Jane is probably not a CHRISTIAN name'? Personally I refer to first or given names.

livelylass. Since I speak neither Hebrew nor Aramaic I cannot comment on the 'correct' spelling of Rebekah. However as the original documents were not written using the modern alphabet it is difficult to know how either 'Rebekah' or 'Rebecca' could be regarded as correct.

Just as with modern Chinese or Arabic, Latin forms are an approximation of the original.

Actually I find it difficult to see how you interpret RB's post as a critisism of modern tredny spelling.
